THOMAS S. MASON, OF CAMDEN, NEW JERSEY, ASSIGNOR TO NEW ORK SHIPBUILDINGCOMPANY, OF CAMDEN, NEW JERSEY, A CORPORATION OF NEW JERSEY.

CALKlNG-TOOL.

Specification of Letters Patent.

Application filed April 20, 1905. Serial No. 256,658.

Patented Jan. 23, 1906.

To all whom it may concern:

Be it known that I, THOMAS S. MASON, a citizen of the United States ofAmerica, residing in the city and county of Camden, in the State of NewJersey, have invented a certain new and useful Improvement in Calking-Tools, of which the following is a true and exact description, referencebeing had to the accompanying drawings, which form a part thereof.

My invention relates to the construction of calking-tools, and has forits object to provide a tool adapted for the preliminary operation ofpinning the oakum into the seam to be calked preparatory to the actualoperation of calking by driving and compacting it into the seam; and mynew tool consists, essen tially, of a blade adapted to enter the seamand formed on its working edge with a series of blunt projectionsseparated by recesses.

This blade can of course be attached to any convenient handle; but Ipreferably use it in combination with aspecial shank and handle, asshown in the drawings.

In the drawings, Figure 1 is a perspective View ofa portion of a shipsdeck, showing the nature of the work to be done by my new tool. Fig. 2is a side elevation of the tool; Fig. 3, an edge view thereof, and Fig.4. a plap looking toward the working edge of the too A is the deck to becalked; a a, &c., the seams.

B is the yarn of oakum which by the action of my tool is pinned into theseams a, as shown at B, while at B I show the yarn packed or calked intothe seams.

D is my calking-tool proper, formed of a steel blade, the working edgewhereof is formed into a series of blunt projections D, separated byspaces (1.

C is the shank or handle for the tool,formed with a button-like head Cand with a broadened-out tool-holding portion C slotted to receive thetool, as shown at 0 E E, &c., being rivets by which the blade is held tothe shank.

In operation the oakum yarn is fed to the seam, as shown at B, and theoperative then works along the seam with my tool, pinning the oakum tothe seam, as shown at B, my new tool enabling the work to be done muchmore rapidly and evenly than has heretofore been found practicable andwith the further result that the completed calked seam is bet:

ter than when the preliminary pinning of the oakum in place has beeneffected by such tools as have heretofore been used.

Having now described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. A calking-tool having a blade adapted to enter the seam to be calkedand formed with a series of blunt projections D, separated by recesses(Z.

2. A calking-tool having a shank or handle C, provided with an expandedhead C, and an elongated and slotted tool-holding portion C incombination with a blade D, inserted and secured in the slotted portionC and formed with a series of blunt projections D.
